Re: Question regarding fasting on 12th rabiu-awal
Allah has indeed shown grace to the believers in sending them a messenger from among themselves who reciteth unto them His revelations, and purifieth them and teacheth them the Book and Wisdom (3:164).
These are the functions of the Prophet (PBUH). Revelations=Quran. The other 3: purifying, teaching the book and wisdom. There is the evidence from the Quran.
It is one thing to not understand the message of the Quran, it is another thing to propagate it without understanding. If you want to believe what you just wrote and quoted, then so be it, but please do not try to convince me that this is what 3:164 is saying.
Al-Kitaab does not necessarily mean "book"; it means LAW (especially from Jahiliyyah Arabic point of view), the same way TAURAA means Law in Hebrew. So try to translate the verse now:
لَقَدْ مَنَّ اللَّهُ عَلَى الْمُؤْمِنِينَ اِذْ بَعَثَ فِيهِمْ رَسُولًا مِنْ انْفُسِهِمْ يَتْلُوا عَلَيْهِمْ ءايَتِهِ وَيُزَكِّيهِمْ وَيُعَلِّمُهُمْ الْكِتَبَ وَالْحِكْمَةَ وَاِنْ كَانُوا مِنْ قَبْلُ لَفِي ضَلَلٍ مُبِينٍ
God did confer a great favour on the believers when He sent among them an apostle from among themselves, rehearsing unto them HIS SIGNS, sanctifying them, and instructing them in THE LAW and THE WISDOM, while, before that, they had been in manifest error.
THE LAW and THE WISDOM is IN the SIGNS OF GOD... i.e. the Great Reading: Quran. The law prescribes what to do and the wisdom (contained within the message of the Quran) tells you why.
Secondly, who are these "believers" amongst whom the exalted messenger is sent? And second, what did the prophet's people say to the him according to the Quran:
وَجَدنَا عَليْها آباءُنا واللّه أمَرنَا بِهَا
And we saw our elders on this (path) and God has prescribed it for us.
Sounds very much like the rhetoric of those who say they follow "sunnah" (be they sunni or shia or anyone who follows for sake for following)
